"These guys are the BEST! Fast, efficient, good natured, innovative and the highest quality of craftsmanship! Project started just to fix woodshed, however it was too far gone so it came down. I saw visions of new project same time Ian did. He drew up plans the next day and I now have a woodshed and screened in back porch. I wanted them to preserve the integrity of my old house and use as much from the old woodshed as possible, barn siding, windows and church pews that came out of the house when converted from a church in 1836. So amazing! Thank you!"
